What i ended up doing was i kept messing with it and adding new batteries untill i accidentally cleared the ram, but in doing so, i figured out what i did. we must have set the brightness up too much, and so the whole screen is white, so it looks like it is off. just press the on button and press second and hold the up arrow untill you can see something on your screen again.

It may be that your contrast is too light. turn the calculator on (it will not seem like it) then proceed to press the 2nd button then click the up button a few times to return to normal contrast.

Mine was acting up to. I found somewhere that the no/slow key response could be due to a short in the I/O socket. I blew into it really hard, and it worked perfectly after that. I hope this helps.

MTG 900 SAYING "CHARGE" AND I'VE BEEN PUTTING


I am assuming you are reading the battery charge correctly. If so you need a new rechargable battery. Special battery so it is a little expensive. Make sure the person knows it is a "rechargable battery" you want. A regular battery will not work properly or recharge.

Car would not start. we put a new battery in it worked then after a 100 mile trip we parked it at home and now it won't start. The lights all light up no clicking just silence


there 2 things that could possibly causing your problem either the battery you just bought isn't good aare you've got and alternator problem... Are you've been leaving something turned on, on the car that runs down the battery. let me know what happens.. Most of the Lexus have those problems.

My 2007 corolla won't start. When I turn the key in the ignition the starter makes a rapid clicking noise. I?ve tried putting the car in neutral and starting it that way, but had no luck. I?ve also tried...


1st check the main cable to the starter make sure it is clean and tight, disconnect battery first, after that there should be a small wire going to the starter jump that small connector to the main battery cable on the starter (IGNITION OFF) if it cranks you have a wiring or ignition switch problem if not Starter time just make sure you get a very good quality starter some cheap and even lifetime starters are so poorly made that even after you replace them you still have a problem only a bad noise coming from the new starter you just put in.

Dell Inspiron 531 (desktop) won?t turn on/boot


You've either got a bad motherboard or a bad processor (I'd lean to the motherboard being bad). I would honestly take this into a computer repair shop and have them check both.

I ve just opened the box and turned on phone.Nothing on screen!


send it back. It sounds like even if your were to fix this by taking out the battery and putting it back in, it should not do that new. Get it replaced ASAP
